【Function interpretation】Why add a diode between BAT and VDD for SS880X, SS881X and other chips?
Jan 30, 2021, 6:17 PM
First of all, we need to understand the concept that the power supply node of the SS880X and SS881X has only one (VDD). This is determined by the power architecture of the two ICs. As shown in Figure 1, whether it is powered from SPWR/VKEY, VIN or VDD, the power supply must eventually pass through VDD to supply the entire system.
